Problem solved. To improve WAF, I had written a frontend watcher
script which tries to restart the frontend if it finds it not running
(i.e., crashed). The script was launched from rc.local using the
su -c '/home/mythtv/bin/watch_frontend.sh &' mythtv
The "su" command needs to be run with "-l", otherwise $HOME is
certainly wrong, and likely inaccessible.
This also fixed my problem where the Mythbuntu and some other themes
would delay 1-2 seconds between items on the Watch Recordings page.
